My comments will be somewhat less ecstatic than others. I preferred the "domino theory" of which this book is the result. The conditions and survival situations in this post-apocalyptic world are fairly well worked (disorientation, conditions for women ...). I came against the strings to lead us from one story to another are a bit too large and sometimes too caricatured characters. Well after that remains in the style of the American disaster novels (by British writer).
